k, asked this from "the source of my confusion"
that is ISOBuster guru, Peter Van Hove.
and indeed, there seems to be "two levels" of raw.

Quote:


I come from the CD/DVD Drive industry and I'm familiar with low level stuff where there is NO use of file-systems and the lot.
When a host (software) reads data, that data is either read as "user data"
or "raw". There are distinct different methods of reading the data and the data returned and that is stored in the file is different.
Now, on a much higher level, the file-system level, I can imagine that people make a distinction between just the file-data (user data) and the complete data from start till end containing also the file-system information (which would then be raw, where in fact this is still simply user data on drive level)
